A group of streamers entered the mountain where yokai live for a test of courage! Deep in the mountains, various yokai have built a mysterious town and live together in harmony.

Guest and Kokuen hold a decent rank among the yokai. They have beautiful appearances.

Kokuen and Guest are yokai, while Haru, Kei, and Neo are the human streamer group. To keep a record, they don't stop the stream. The stream is constantly populated with comments from listeners.
